Clam Tavern at 339 East Broadway Avenue, Clifton Heights, Pennsylvania.

Okay, having been here four times now, I'm editing my review to 5 stars. Original: If not for the sketch exterior, I'd give this place five stars. The food is great, service friendly and attentive, and the beer cold. Clams casino are very tasty. Raw oysters expertly shucked. Stuffed shrimp rich and flavorful. Steak done perfectly. Everything is super fresh. It takes a bit of courage to enter from outside, but I love finding gems like this. I'll be back.
